Stripping paint off Boxxers (or other Rockshox)

My worldcups are absolutely hammered, almost as much bare metal as there is paint... Surface is too bad to just spray over, and sanding back to the metal is a lot of work. But nitromors didn't so much as dent it, and my wire wheel is too aggressive- it's leaving scratches in the lowers! Any suggestions to save my arms from sanding hell?

I think for a decent looking job having the lowers dipped would be the way to go , for a real bodge it and scarper route how about a good clean/degrease and the sand for a key and fill in the chips withcar body filler and sand smooth?
Then spray with plasticote black or white and new decals off ebay
